Definition and Origin

"Coalbed methane (CBM) is methane contained in coal seams, and is often referred to as virgin coalbed methane, or coal seam gas." (EPA Climate Change Glossary of climate change terms) It refers to the methane gas found in coal deposits.

Coal Mine Methane (CMM) is the subset of CBM that is released from the coal seams during the process of coal mining. The CMM described and discussed in this Wiki is an anthropogenic emission.
